The CIA recently tweeted photos of the new fall class of K9 operatives — dogs training to work in the field. The CIA's website introduces the "Fall '17 Puppy Class":

Most people have no idea that the CIA has its own K9 Corps; however, our K9 officers serve as the first line of defense against explosive threats to Agency personnel and buildings at Headquarters and abroad. Additionally, they are on-call 24/7 to assist local law enforcement and other federal government agencies search for explosives.
